Maybe I have to give these albums a few more listens, I love Child In Time, great song!
Funny I like Gillan's and Hughe's voice best on the Sabbath albums they performed on Born Again and Seventh Star, though Seventh Star is more of a IommI SOLO ALBUM.
Everyone loves Machine Head as do I, but something special about the Perfect Strangers album, maybe because it was part of my formative years.
Always loved David Coverdale's voice, from Purple to Whitesnake.
P.S. I forgot to mention I also have Shades Of Deep Purple, the original Deep Purple, not bad as well.
